If there was any chance of this being viable by 2028, they would have a demo car today that works
Car production timelines are LONG
Yes this. If those years were realistic there would be a car we’d be looking at in prototype form.

It requires years of test drives to go to market and get production quantities enough to sell
There is a 0% chance it’s available in 2028 if there isn’t a demo unit today.
It might be in some high end “we’ll sell 1,000 of these cars” by then

They can’t bypass certifications
They’ve also been pushing hydrogen and not working on BEVs while everyone else was working on BEVs
I like your optimism, but this is just marketing fluff that won’t come to market on that timeline
I don’t know if the journalist didn’t understand, or Toyota lied, but it’s not happening by 2028

Engineer in the automotive industry here. Vehicles need a ton of certification by tons of different governments and face very strict regulation.
Just a battery alone is going to be subject to lots of EMC emissions and interference tests. Then you have the capability to survive crashes, fail operational requirements, how does the battery fail (does it explode or just disconnect itself?), etc. etc. These are all dependent on the chassis the battery is in, so they can’t just swap it into an existing chassis and say “Oh it worked with battery A, it’ll work with battery B.” Unfortunately the requirements are just way too strict for that.
Additionally I can’t go into details but the sentiment others are echoing of “If it’s coming in 2028 they should have a functioning prototype” are true in my experience. It takes several years to design and release a car, and when you’re introducing a new battery tech or drive train or similar changes it takes even longer.

Different battery chemistries do not behave identically in terms of failure modes, EMC emissions and interference response, and tons of other things. Just swapping one battery for another has a huge effect even before you consider auxiliary components like charging circuitry.
My assumptions as to why you can just drop in an aftermarket battery and crate motor into an existing ICE vehicle (also, far from any vehicle, it is a relatively niche product) are that A. The batteries are way smaller and aren’t structural to the frame the way they are in BEV-first designs (but this is how we get good range out of them). B. The companies selling these probably aren’t held to the same emissions standards that an automaker is.
Again, these are assumptions, I don’t work in conversions but in BEV designs primarily. I know there’s a ton of red tape for us to even think about changing battery chemistry, and we 100% would have to get all new certifications for it.
Then Toyota has some magic power that all the other car companies I work with don’t
I know Tesla plays fast and loose with NHTSA regulations, but I doubt Toyota will
This battery technology will have to pass safety inspections, just as Li-ion

If they had the ability to test it in a vehicle, they would be shouting about it from the hills rather than this “maybe it might be possible” report that keeps getting shared
It would be magic to get it into a vehicle in 2028. Every other car manufacturer has finalized their designs past that by now, and aren’t going to risk such a massive change this late in the design process
This is part of why the infotainment systems in cars tend to suck. They’re finalized about 6 years before the car goes to market
